Backboard 5V consumes 0.85 A
External power supply does not require external 24V, only backplane power supply
Terminal Block IC693TB2 (Removable Screw Terminal)
Working temperature: 0 ℃~+60 ℃
Humidity 5-95% RH, non condensing
core functionality
16 channel single ended voltage acquisition, all channels share a common reference ground; Ground loop interference can cause reading drift, making it suitable for short distance wiring.
Range software configuration, without hardware jumpers, set channel by channel in PLC hardware configuration.
Built in channel open circuit diagnosis, fault status uploaded to CPU, user program can read fault location for alarm.
Processing 4-20mA signal: An external 250 Ω precision resistor must be connected to convert 4-20mA into 1-5V voltage and connect it to the module.
Terminal allocation (IC693TB2)
CH0~CH15: Analog input signal positive pole
COM: Common negative terminal for all channels (single ended ground)
Without built-in circuit power supply, it cannot directly supply power to the transmitter.
