TR series power modules are plug-in power modules for TELE monitoring relays series GAMMA and TREND for converting the supply voltage at terminals A1-A2 to internal operating voltage 24V~.
The handbook describes the TELE TR2 and TR3 power modules, which convert the supply voltage at terminals A1‑A2 of TELE monitoring relays to an internal 24 V operating voltage. It lists functions, mechanical design (sealed self‑extinguishing plastic housing, IP40), electrical data (nominal voltages from 12 VAC to 415 VAC, consumption, rated load, design type), ambient conditions (‑25 °C to +55 °C) and mounting instructions (5 mm mounting hole).
Additional sections cover accessories such as SK series probes for conductive‑liquid level monitoring, a base load component for mains decouplers, mounting plates and a sealable front cover for GAMMA series relays. Each accessory includes mechanical design, electrical data, ambient limits and mounting guidance.
