IFM DD2503 Speed Monitoring Evaluation Unit

Product overview

The ifm DD2503 (MONITOR/FR-1 /110-240VAC/DC) is a microprocessor evaluation unit for speed monitoring that evaluates frequency, rotational speed, speed, pulses and machine cycles, for DIN rail mounting. Its setting range is 0.1…1000 Hz (1…60000 pulses/min); it has two relay outputs rated at 6 A (250 V AC, 30 V DC) with a resistive load and a 4…20 mA analog output, and supplies sensors with 19.6…27.7 V DC (SELV, up to 15 mA). It runs on 110…240 V AC or 27 V DC, has dual-chamber terminals for conductors up to 2.5 mm² (AWG 14), measures 78 x 45 x 124.7 mm and is rated IP50 (terminals IP20) for -40…60 °C ambient.
