Product Description

CALT SSI Length signal and 4-20mA weight signal three channel data liquid crystal display

★ Joins all brand of SSI signal sensor
★ SSI signal can while redundant equipment connection PLC of SSI module and this paragraph instrument
★ powerful of signal and power anti-interference fault-tolerant function, more reliable security
★Optional signal code: Gray code, Binary code
★ Can connecting 1 set SSI output signal Multi-turns absolute encoder to measure Length, and 1 or 2 sets 4-20mA output signal load cell for weight at the same time.
★ intelligent of Panel set, widely used in length and weight control systems, like Hydraulic Gate control systems and Hoisting operation system.
★ RS485 digital communications, and 4-20mA, and 8 points switch variety output signal

Operation parameter
