Overview
The GD-02K-DIN provides reliable remote control and status monitoring of appliances and systems using standard SMS commands or calls. It integrates control outputs, status inputs, temperature measurement and pulse counting in a compact DIN‑rail enclosure.

Outputs and control
The unit includes two relay outputs (REL1 — power output; REL2 — signal output) configurable as status or pulse outputs (pulse length 1 s – 24 h). Outputs can be operated by SMS, call or local inputs, and custom notification texts can be assigned for state changes.

Inputs and pulse counter
IN1 and IN2 function as universal inputs (active when connected to GND, max. 24 V) and support pulse counting for one or two external meters (electricity, gas, water), including two‑tariff meters. Counter status and limit breaches are reported via SMS.

Temperature measurement and thermostat
A JB-TS-PT1000 digital temperature sensor can be connected to the TH inputs. The module can measure temperature, alert on threshold violations and operate as a thermostat by switching REL1 according to remotely set target and antifreeze temperatures.

Installation and configuration
Designed for DIN‑rail mounting. Configuration is possible locally via MicroUSB using GD‑Link software (v.2.3.0 or later) or remotely via GPRS. The device stores up to 100 authorised phone numbers and includes an internal Polymer Li‑ion backup battery to maintain operation during mains failure.
