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.

Maximum overload at input terminals ±35V DC continuous
