Controller K31HIRRRR, 0/4-20mA, 4 relay outputs, 100-240VAC

K31HIRRRR is an Ascon Tecnologic K31 panel controller in a 78 x 35 mm case for 0/4...20 mA input. It is the controller version, without timer and programmer: control is ON/OFF, neutral zone or PID with single or double action, with self-tuning and two autotuning algorithms, and up to four setpoints can be stored.

• Input: 0/4...20 mA; accuracy ±0.5% fs + 1 digit
• Outputs: OUT1 and OUT2 relay SPDT 8 A-AC1 (3 A-AC3/250 Vac); OUT3 and OUT4 relay SPST-NO 5 A-AC1; 2 digital inputs for volt-free contacts
• Communication: TTL ModBus
• Supply: 100...240 Vac, approx. 6 VA; auxiliary output 12 Vdc/20 mA
• Case: 78 x 35 mm, depth 64 mm, panel cut-out 71 x 29 mm; 4-digit red display, 12 mm, with 3-LED bargraph
• Environment: IP65 front with gasket, 0...50 °C, 20...85% RH without condensation

The 0/4...20 mA input takes a transmitter signal, and the four relays allow two-stage control plus two independent alarms on one process value.

Complies with EMC directive 2004/108/EC (EN 61326-1) and low voltage directive 2006/95/EC (EN 61010-1).
