SPECIFICATIONS (Cont’d)
6. MAXIMUM COUNT RATES :
High Frequency : For the single preset unit only - 15 KHz max. square wave
input for all electronic sensors, under all modes of operation. For dual
preset units, the following chart lists the count rates for all the possible
prescale values.
DUAL PRESET UNITS ONLY
Prescale Value Frequency
0.00001 to 1 12 KHz
1.00001 to 2 9 KHz
2.00001 to 3 7 KHz
3.00001 to 4 5.5 KHz
4.00001 to 5 4.5 KHz
5.00001 to 6 4 KHz
6.00001 to 7 3.5 KHz
7.00001 to 8 3 KHz
8.00001 to 9 3 KHz
9.00001 to 9.99999 2.5 KHz
Note: For prescale values greater than 7, the timed delay output is affected
by the count speed (rate).
Low Frequency : both single and dual preset units - 100 Hz for switch
contact closures. Note: These units will operate with VCM (E through H)
modules.
7. CONTROL INPUTS : Active low (V IL = 0.5 V max.), internally pulled up
to 5 VDC through a 10 K ? resistor (I SNK = 0.5 mA).
Remote Reset : Response time = 10 msec. A low will reset the unit and
deactivate outputs.
Program Disable : A low will inhibit the changing of presets, prescale, and
timed outputs, as well as testing outputs in self-test.
Up/Down Control: Response time = 150 μsec. A low will cause the unit to
count down. A high will cause the unit to count up.
8. OUTPUTS :
Solid-State : Current sinking NPN Open Collector Transistors.
I SNK = 100 mA max., V OH = 30 VDC max., V OL = 1 V @ 100 mA.
Relay : Form C contacts max. rating 5 amps @ 120/240 VAC, 28 VDC
(resistive load), 1/8 H.P. @ 120 VAC (inductive load). The operate time is
5 msec. nominal and the release time is 3 msec. nominal.
Relay Life Expectancy - 100,000 cycles at max. rating. (As load level
decreases, life expectancy increases.)
Programmable Timed Output : The timed output can be programmed from
0.01 sec. to 99.99 sec., ± 0.1% + 10 msec. The timed output is set for 0.1
sec. at the factory.
9. MEMORY RETENTION : Non-volatile E 2 PROM retains all programmed
information when power is removed or interrupted.
10. INPUT, POWER, AND OUTPUT CONNECTIONS : Removable
terminal blocks.
11. ENVIRONMENTAL CONDITIONS :
Operating Temperature : 0 to 50°C
Storage Temperature : -40 to 70°C
Operating and Storage Humidity : 85% max. relative humidity
(non-condensing) from 0°C to 50°C.
Altitude : Up to 2000 meters

Notes:
1. Power lines had an external EMI line filter (RLC #LFIL0000 or
equivalent) installed.
2. I/O cables routed in metal conduit connected to earth ground.
Refer to the EMC Installation Guidelines section of the bulletin for
additional information.
13. CONSTRUCTION : Black plastic front bezel with black plastic insert.
Front panel meets NEMA 4X/IP65 requirements for wash-down and dusty
environments, when properly installed. Installation Category II, Pollution
Degree 2. (Panel gasket, mounting clip, nut fasteners, and screws included
with unit.)
14. WEIGHT : 0.8 lbs (0.36 kg).
FRONT PANEL FUNCTION DESCRIPTION
The units employ eight front panel buttons for control and data entry. The
button functions are as described below:
RESET “R”: Resets the counter to either zero or preset, depending on the
mode of operation selected. For this button to operate, the enable/disable
reset switch at the rear of the unit must be set to the enable (EN.) position.
The reset button is also used in conjunction with the preset button(s), to view
and change the timed output value(s). When reset is activated, all processes
are stopped or interrupted (i.e. outputs turn off, display is reset, etc.). This is
the case under any mode of operation, in any data entry mode.
PRESET “P1” (“P2”): Labeled P1 and P2 (single preset units only have the
P1 preset button).
The preset 1 value is displayed when the P1 button is pressed, and the Preset
Value mode is accessed (See Program Preset Value). The value remains
displayed for approximately 10 seconds after the button is released. The
preset buttons are also used, in conjunction with the reset button, to view and
change the timed output values (See Program Timed Output Value section.)
ENTER “E”: Used when programming the Preset Value or the Timed Output
Value. After the desired value is obtained on the display, pressing the E
