I will post some of the manual for the Durant 1000 series counters. This is my random contribution to the forum here. I have installed and replaced tons of these counters early in my career. These counters are long obsolete...
GENERAL DESCRIPTION
The Series 1000 2, 3 or 4 digit, single level, Solid State Count/Control is a high noise immunity, solid state LED count display control using CMOS (Complementary Metal Oxide Semiconductor) integrated circuits and Durant bi-directional pushbutton selector switches.
The input circuit allows for selection of, and is optimized for, slow speed contact closures, for high speed solid state inputs and for a wide variety of transducers.
The input will accept all Durant transducers; shaft encoder 39300-XXX; miniphotocell 39200-400; retro-reflective photocell 49160-401; rotary and lineal contactor ES9513-RS; mercury wetted reed switch sensor 49485-400; zero speed vane pickup sensor 39400-400; and the proximity sensor 49434-400.
The count input can be inverted so that a count is entered when initiated or at the end of the count input. (When a photocell light beam is interrupted or when the light beam is re-established.)
The output consists of a relay with two 10 ampere 120VAC or 28VDC form "C" contacts. The relay operates in various modes selected by jumpers on the rear panel terminals. Relay operating modes which can be selected are: latch until reset signal is complete; latch until an external contact is closed or 100 millisecond time out.
The timeout duration can be increased up to 10 seconds by substituting a resistor for the rear panel terminal jumper.
The Series 1000 has a front panel reset switch and rear panel terminals are provided for a remotely located reset switch. Automatic reset at coincidence can be selected at the rear panel terminal by using a jumper.
Automatic reset provides for automatic recycling of the control without loss of counts, automatic reset at coincidence to permit measurement of the overshoot or over count after coincidence, etc.
SPECIFICATIONS
I. Power Requirements
120VAC +10% - -20% 50/60 Hertz. Power is connected to the rear panel terminals provided, including chassis ground.
The power circuit is connected directly to the input power transformer primary without power switch or fusing.
Nominal wattage for a 4 digit unit is 6 watts with display, 5 watts without display. Maximum current is 0.1 amp with display, 0.08 without display.
II. Counter and Coincidence
A. Number of digits: 2, 3 or 4.
B. Coincidence selection: Bi-directional switches.
C. Characteristics:
Turn on to all zeros. (Higher order zeros blanked.)
Reset must override count.
Coincidence with count input only.
Display of power "ON" by LED indicator and change in the LED
light intensity as manual contact closure count inputs are made.
D. Counter reset functions:
Front panel switch (depression of a momentary toggle switch).
External contact (circuit) closure to power supply common.
Automatic recycle with coincidence. (Jumper recycle terminal to
+15VDC.)
Maximum immunity to reset contact bounce, contact noise or
external electrical noise (Schmitt Trigger reset input).
When reset switches are used to terminate the relay actuation
output, the output is to terminate with the release of the switch
(latch until reset is completed).
III. Output Control
A. Two form "C" contacts rated 10 amperes resistive at 120VAC or 28VDC.
B. Output relay functions selectable at rear terminals. Timed 100 milliseconds (jumper time out terminal and+15VDC)

C. Count output is provided to operate a second Series 1000 control or other logic circuit. This output assures compatibility of any other unit even with variations in production and short on or off time for the count input. Count Inputs (Always connect count input between input terminal and common.)
A. Count circuit input to 5 kilohertz. Includes operation for most all
Durant transducers which are not better suited to slower count speed
of "B".

photocell goes dark, etc. (Connection is to be made between the
"invert" terminal and common. Count input must be made per IV.

6. 15VDC positive (added terminal to facilitate wiring).
7. 15VDC common (added terminal to facilitate wiring).
8.
9. Timed output (jumper time out terminal to +15VDC for 100 milliseconds or add resistor in lieu of jumper, for time out up to 10 seconds).
10. Latch until reset is complete (jumper LURCterminal to+15VDC).
11. Auto recycle (jumper auto reset terminal to +15VDC).
15. Latch until external contact closure or circuit is made (connect switch or circuit between unlatch terminal and common).
17. Counter reset (connect remote reset switch between reset terminal and common).
VI. Displays
A. .300 inch LED count display.
B. Optional decimal point of LED count display optionally availab
C. Power "ON" and counting LED indicator. In this case an LED
lite is to operate with power "ON" and to reduce in intensity
count input so that counting is visually apparent at low speed m;
count contact closures.
D. Ripple blanking of higher order zeros.
VII. Weight
Chassis maximum volume is 64 cubic inches. The weight is 3 pou for the Series 1000 and 1.2 pounds for the desk mount chassis.
