Digital Input Module ASDCM-8D
- Commodity name： Digital Input Module ASDCM-8D
Product Details
- Product Description
-
Performance Overview
The industrial‑grade isolated digital I/O module complies with the standard MODBUS‑RTU communication protocol. Internally, it features a 16‑bit ADC and an advanced smart processor, supporting a wide range of configuration software and PLC systems. It is designed for various digital signal acquisition and control applications. The device operates at a supply voltage of DC 9–32 V, mounts on a standard DIN rail, and employs opto‑isolation between its communication interface and digital input/output channels. Additionally, the communication interface incorporates ESD and surge protection.
Technical Specifications
1. Signal:
- 8-channel DI: NPN, PNP, dry contact
- 7-channel DO: Relay contacts
2. Sampling Rate:
- DI: 240 sps (typical value);
3. Relay contact rating: 5 A, 250 V AC; 5 A, 30 V DC
4. Communication Interface:
- Physical Layer: RS485
- Baud rate: Default 9600 bps; configurable to 2400 bps, 4800 bps, 19200 bps, 38400 bps, 57600 bps, or 115200 bps. Protocol: MODBUS-RTU.
- Communication distance: ≤1000m
5. Status indicator light:
- PWR: Power indicator; remains steadily lit when the module is operating normally.
- TXD: Master station communication status indicator; the light flashes during normal communication.
- RXD: Device communication status indicator; the light flashes during normal communication.
6. Dielectric Strength: 1500 V AC (between the DI and RS485 communication interfaces and the power supply, with a leakage current of 1 mA); 3000 V AC (between the DO, DI, and RS485 communication interfaces and the power supply, with a leakage current of 10 mA).
7. Electromagnetic Compatibility: EMC complies with IEC 61326‑3‑1 □ Power Consumption: Less than 1 W when powered by 24 V DC.
8. Supply voltage range: 9 V DC to 32 V DC
9. Operating temperature: -20°C to +60°C
