Discrete Outputs The following table contains specifications for discrete outputs.
Description Solid state switch

Absolute Minimum Voltage 12 VDC
Absolute Maximum Voltage 45 VDC
Maximum Voltage 50 VDC for 1 ms
Number of Points 8
Number of Groups 1
Points per Group 8
Current Capacity 250 mA per point 2 amps per module
Type of Signal True high (sourcing)
Leakage Current < 1 mA @ 42 VDC
Surge Current 5 amps for 1 ms
On State Voltage Drop < 1.0 VDC max at 0.25 amp current
Fault Sensing Overload and short circuit
Fault Reporting System bit
Response Time 1.8 ms OFF to ON
1.8 ms ON to OFF
CAUTION
Discrete VDC outputs incorporate thermal shutdown and overload
protection.
The output current of a shorted output is limited to a nondestructive
value. The short circuit heats the output driver, and the output will switch
off. The output will switch on again if the driver leaves the over
temperature condition and the user resets the output under program
control. If the short circuit still exists after the output point is reset, the
driver will reach the over temperature condition again and will switch off
again.
Failure to follow this precaution can result in injury or equipment
damage.
