Model TMZ accepts most industry standard temperature, current or voltage signals. The PC-programmable Modbus transmitter with dual universal input channels allows users to increase measurement density. The digital Modbus output reduces error that is inherent on analog 4 to 20mA output transmitters due to their required D/A conversion. Because measurements from both inputs are available on the Modbus output, the host system has the option of monitoring each point individually or combining the readings for backup/failover, averaging or differential measurement strategies. Also, the input terminal temperature reading used for cold junction compensation on thermocouple inputs is available on the Modbus output, which can be used for determining ambient or internal cabinet temperatures.
