Microprocessor controller available in 48x96 mm (1/8 DIN) format for model 1000, and 96x96 mm (1/4 DIN) format for models 1001 and 1101, built using SMT technology.
The 1000 series provides a complete operator interface with a Lexan membrane front that ensures IP54 protection. It features 3 keys, dual green LED displays (3 digits for 1000, 4 digits for 1001/1101), red LEDs for up to 3 alarm relays, and a green LED for the main output.
The main input is universal, supporting multiple signal types:

• Thermocouples: types J, K, N, S, R, T
• Resistance thermometer: Pt100 (3-wire)
• Linear signals: 0–50 mV, 10–50 mV (keyboard-definable), 2–10 V, 0–10 V, 0–20 mA, 4–20 mA (with external shunt)

An auxiliary analog input is included for current transformer (C.T.) signals.
The device offers dual outputs: relay (5 A, 250 VAC, cosφ=1) and static (24 Vdc, max 20 mA), with up to 3 alarm relay outputs (3 A, 250 VAC). Alternatively, the main output can be analog (0–20 mA, 4–20 mA, 0–10 V, 2–10 V).
Optional communications include Current Loop or RS485 with GEFRAN (Cencal) protocol at up to 9600 baud.
Programming is simplified with parameters grouped into function blocks, and access can be restricted using a hardware jumper and adjustable protection codes.
