Excitation Current Source
0.5 mA and 1.0 mA selectable per channel
Open-Circuit Detection Time
(2)
6 to 303 ms. Open-circuit detection time equals Channel update time. See Determining Module
Update Time on page 4-26.
Channel Update Time
Input filter and configuration dependent.
Input Channel Configuration
via configuration software screen or the user program (by writing a unique bit pattern into the
module’s configuration file). Refer to your controller’s user manual to determine if user program
configuration is supported.
Calibration
The module performs autocalibration on channel enable and on a configuration change between
channels. You can also program the module to calibrate every five minutes.
Module OK LED
On: module has power, has passed internal diagnostics, and is communicating over the bus.
Off: Any of the above is not true.
Channel Diagnostics
Over- or under-range or broken input by bit reporting
Maximum Overload at Input Terminals
Voltage: ±30V dc continuous, 50 mA
Current: ±50 mA continuous, ±30V dc

Power Supply Distance Rating
8 (The module may not be more than 8 modules away from the system power supply.)
Channel to Bus Isolation
720V dc for 1 minute, optical and magnetic (qualification test)

(1) Repeatability is the ability of the module to register the same reading in successive measurements for the same input signal.
(2) Open-circuit detection time is equal to channel update time.
