Design and Energy Storage
This unit stores minimal energy in small filter capacitors. Each channel includes an isothermal block for cold junction reference. The module automatically linearizes millivolt signals to temperature values. Surface-mount technology boosts reliability in industrial environments. Furthermore, this thermocouple module has LED indicators for each channel’s activity.
Installation and Connectivity
You can mount this module into any Series 90-30 rack slot. It accepts field wiring via a removable terminal block. A shielded cable reduces electrical noise on thermocouple leads. Consequently, you complete the installation within a few minutes. Finally, software configuration selects the thermocouple type per channel.
Performance and Temperature Measurement
This unit consumes only 2.5 watts during normal operation. Its 16-bit resolution provides precise readings across wide temperature ranges. Thus, you get accurate data for furnace and kiln control applications. The module detects open thermocouple conditions automatically. This device also features 250V AC isolation between channels and backplane.
Typical Applications
Use this thermocouple module for monitoring exhaust gas temperatures. It also excels at heat treating and annealing furnace control. Many plants select this unit for plastics processing and extrusion lines. The compact module design saves valuable rack space effectively. Finally, built-in diagnostics alert you to sensor faults immediately.
