Product Description
The Nachi EMC-PC6-A-20 is a 6-channel Controller Type power amplifier from Nachi-Fujikoshi's EMA/EMC Series, designed for driving electro-hydraulic proportional pressure, flow, and directional control valves. It performs multi-stage control of output current in response to ON/OFF signals from external contacts such as relay contacts, limit switches, or timer contacts. The unit features built-in command voltage setting potentiometers for each channel, internal dither adjustment, and supports both AC100/110V and AC200/220V power supply inputs.
