Designed specifically for power control purposes, the T40H-Relay offers 16 high current (10A @ 250V AC), isolated relay outputs with 8 common terminals (every two output shares one common). The 2500VA contact rating for every output makes T40H-Relay and its sibling - T28H-Relay the only true power controllers in the industry.

Each T40H-Relay controller comprises 24 bi-directional opto-isolated inputs, 16 outputs, 128 internal relays, 20 timers, 20 counters and 8 sequencers. In addition to basic high speed AND/OR/OUT instructions, T40H supports a number of useful special functions such as sequencers, reversible up/down counters, differentiated instructions and latch relays to handle the most demanding applications.

Main Features

  • On-board Power Supply which accepts a 12V AC inputs
  • 24 bi-directional, opto-isolated Inputs with LED indicators. Easily interface to 9 ~ 24V sensors with either PNP or NPN type interface.
  • 16 Relays Output each is capable of conducting 10A @250V AC continuously
  • Programmable in Ladder Logic software with SIMULATOR - TRiLOGI
    - Creates ladder program using meaningful names
    - Uses simulator to fully test programs on the PC screen before downloading
    - On-line monitoring of all I/O logic states on ladder diagram or on full screen
  • Networkable by RS485 (two-wire) bus
    - Built-in RS485 adapter. Each controller can assume an 8-bit ID. Host computer can access any controller linked to it by just two wires!
  • EEPROM program storage (400 steps, 40 years)
  • Compact size. Only 19.5cm (L) x 12.0cm (W) x 3.0cm (H)
  • Detachable screw terminal blocks
