Description
The TCR‑102 series consists of compact, DIN‑rail mountable relay modules with two SPDT channels, designed for direct control via 3.3V or 5V TTL logic signals. The input stage supports standard TTL switching thresholds:
- LOW: 0.0–1.0 V
- HIGH: 1.8–5.0 V
This ensures reliable operation with a wide range of embedded systems and microcontrollers. The input circuitry draws minimal current, making the module ideal for low‑power and battery‑operated environments.
Each unit is housed in a robust green plastic enclosure, with three status LEDs indicating power and relay activation. The module is engineered for high reliability and seamless integration in automation systems, embedded control, and remote installations.
