The PH electrode has a single cylinder that allows direct connection to the input terminal
of a PH meter, controller, or any PH device which has a BNC input terminal.
The PH electrode probe is accurate and reliable that can gives almost instantaneous readings.
1. 5V 2-Channel Relay interface board, and each one needs 15-20mA Driver Current, optocoupler isolation.
2. Equiped with high-current relay, AC250V 10A ; DC30V 10A
3. Standard interface that can be controlled directly by microcontroller
the use of solid state relays, output with a resistive fuse 240V 2A.
Size: 55 * 33 * 25 (L * W * H)
input power: 5V DC (160MA)
the input control signal voltage:
(0-1.5V state low level relay ON)
