Industrial T121 Universal Temperature Transmitter

Seneca T121 is an isolated, loop-powered temperature transmitter designed for head-mount installation in industrial machinery, plants, and process facilities. Its universal input accepts thermoresistance signals (Pt100, Pt1000, Pt500, Ni100), thermocouples (J, K, R, S, T, B, E, N), and ohmic/mV configurations, with support for 2-, 3-, or 4-wire sensors, and it converts the signal to a 4-20 mA loop-powered output while providing galvanic isolation between input and output. Power is supplied from a 7 to 30 V DC loop, and the device features push-wire spring terminals for fast connections along with SENECA's EASY SETUP software for configuration, simplifying installation and maintenance. With an operating temperature range of -40 to 85 C and a compact head-mounted form factor, the T121 is designed to preserve data integrity in noisy environments, delivering reliable signal transmission across the measurement loop in industrial applications.
