tHAT4 - IDC10 overlay

tHAT4 is an expansion board designed for Lan Controller 3.5+ series devices, offering additional control and communication capabilities.

The board contains:

• 4 open-collector (OC) outputs, controlled from Lan Controller's PWM outputs – intended for driving relays,
• 2 IDC10 connectors, prepared for use with 4×10 A relay boards:
  • one with OUT1–OUT4 lines,
  • the other with PWM0–PWM3 lines and a 3.3 V,
• A green screw connector (block terminal) with leads:
  • A+, B– (RS485 – Modbus RTU bus)
  • INPA5, INPA6 (analog inputs),
• Serial port breakout: +5 V, Rx, Tx, GND (for optional pin or wire soldering).

Compatibility

• Full compatibility with LK3.9 and LK3.7+ controllers (HW 3.7 and HW 3.8).
• In LK3.5 and LK3.6 models - Modbus converter (RS485) is not supported.
