DescriptionThe OM-WLS-TC is a wireless USB 2.0 full-speed thermocouple input module (fully compatible with both USB 1.1 and 2.0). The OM-WLS-TC provides 8 differential thermocouple input channels. Eight independent, TTL compatible digital I/O channels are provided to monitor TTL level inputs, communicate with external devices and to generate alarms. The digital I/O channels are software programmable for input or output. The OM-WLS-TC supports Types J, K, T, E, N, R, S and B thermocouples. Two integrated cold junction compensation (CJC) sensors are included for thermocouple measurements. An open thermocouple detection feature allows detection of a broken thermocouple. An onboard microprocessor automatically linearizes the measurement data. The OM-WLS-TC features 8 independent temperature alarms. Each alarm controls an associated digital I/O channel as an alarm output. The input to each alarm is one of the temperature channels. The output of each alarm is software configurable as active high or low. The temperature threshold conditions to activate each alarm are software programmable. When an alarm is activated, the associated digital output channel is driven to the output state. All configurable options are software programmable. The OM-WLS-TC is fully software-calibrated.
