OK
The module receives power from the backplane power supply. No external power source is
required for module operation. Power for the user’s transceivers must be supplied from an
external source.
Intelligent processing for this module is performed by the CPU or NIU. The module
provides 8 words of analog input data.
LED Indicators
The green OK LED is on when backplane power is present, internally generated field
power is functioning properly, the module has been configured, and the module has been
recognized on the backplane.
Diagnostics
The module reports a Loss of Internal Power fault for field-side circuits.
The module reports an Open Wire fault for each channel, when in 4-20mA mode.
Configuration Parameters
A jumper on the carrier terminals can be used to configure 4-20mA or 0-20mA input
ranges. With no jumper installed, the module accepts 4-20mA input signals. With a
jumper installed, the module accepts 0-20mA input signals.
