EC3 series is the most economical solution for sequential control and communication monitoring and can operate independently, allowing the user to achieve stand-alone monitor, e.g. monitoring phototransistor coupler, proximity switch, optical sensor, indicator and illumination switch. Through serial ports, EC3 is able to connect to control devices such as PLC, frequency inverter and temperature controller, which can be said to be a programmable application solution that is cost-friendly and highly reliable MPU points: 10/ 14 / 16 / 24 / 32 / 60 Max. I/O points: 60 Program capacity: 4k steps COM ports: Built-in RS-232 and RS-485 ports (available in 16-60 point models); compatible with Modbus ASCII/RTU protocol Built-in 4 points of high-speed counters DVP10EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 6 DO 4 Relay DVP10EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 6 DO 4 Transistor DVP14EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 8 DO 6 Relay DVP14EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 8 DO 6 Transistor DVP16EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 8 DO 8 Relay DVP16EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 8 DO 8 Transistor DVP20EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 12 DO 8 Relay DVP20EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 12 DO 8 Transistor DVP24EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 12 DO 12 Relay DVP24EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 12 DO 12 Transistor DVP30EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 18 DO 12 Relay DVP30EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 18 DO 12 Transistor DVP32EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 16 DO 16 Relay DVP32EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 16 DO 16 Transistor DVP40EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 24 DO 16 Relay DVP40EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 24 DO 16 Transistor DVP48EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 28 DO 20 Relay DVP48EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 28 DO 20 Transistor DVP60EC00R3 Delta EC3 Series Standard PLC 100-240VAC DI 36 DO 24 Relay DVP60EC00T3 Delta EC3 Series Standard PLC 100-240VAC DI 36 DO 24 Transistor Payment : we only accept Paypal for online shopping.shipment:We use DHL,EMS as shipment method in normal.Guarantee:1 year quality warranty.
