T121 is a high-precision temperature transmitter for head mounting and is designed for universal use on machines, plants, installations, and in the process industry to facilitate time, measurement costs, commissioning, and maintenance.
The device converts the input signal from Cu50, Cu100, Pt100, Pt500, Pt1000, Ni100, Ni120, Ni1000, TC probes (J, K, R, S, T, B, E, N, L), potentiometer, mV, and retransmits it into a normalized current signal through a 4..20 mA loop-powered (2-wire technology) with 16-bit resolution. The transmitter is characterized by a high operating temperature range (-40..85°C), small size, fast connections via push-wire spring terminals, and 2-way galvanic isolation among input//output assuring the integrity of your data. T121 is certified ATEX II 3G Ex nA IIC T4 Gc X (gas) and II 3D Ex tc IIIC T135°C Dc X (dust).
All operating parameters can be configured via Windows software using a USBUART TTL converter such as EASY USB or S117P1 converter (USBRS232, RS485, UART TTL).
