Process indicator SRP-77 series

ratespeedtilt

The SRP-77 meter is designed for measuring of typical current or voltage signals. The main advantages are two rows of display. The first one presents measuring value, second one - programmed values: max. and min. 1 or 2 relay (or OC) outputs make it possible to control processes ON/OFF type. Current input has protection safeguarding of the measuring resistor against damage. The device is dedicated to aplications, where there is necessity of continuous control of the threshold values. The RS-485 enables data transmission in production process monitoring systems. The REL / OC control outputs can adjust the level of measured signal and are controlled according to one or two threshold values. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port. Output type - Open Collector: I=30 mA, U=30V DC, P=100 mW relay I=1A, U=30V DC/250V AC (cosø=1) Power supply - 16...35V AC, 19...50V DC 85..260V AC/DC 11,4...15V AC/DC Display - LED, double: 4 x 13 mm (red) + 4 x 10 mm (green) Communication Interface - RS-485 / Modbus RTU Transmission parameters - 1200...115200 bit/s, 8N1 / 8N2 Operating temperature - 0...+50°C -20…+50°C
