This manual introduces the Delta CTA series timer, counter, and rotator devices. It includes safety warnings, installation steps, button functions, mode settings, and communication configuration. Detailed diagrams show LCD indicators, key operations, and wiring connections for both AC and DC power supplies.
Technical specifications such as power input ranges, output types, temperature limits, and RS‑485 Modbus communication parameters are listed. The document also explains parameter programming, lock modes, and troubleshooting tips for reliable operation in industrial environments. This manual is written in Chinese.
| Power input (AC) | 100‑240 V 50/60 Hz |
|---|---|
| Power consumption | < 10 W |
| Relay output | AC 250 V 5 A (single‑pole single‑throw) |
| Operating temperature | 0 °C ~ +50 °C |
| Storage temperature | -20 °C ~ +65 °C |
| Input voltage range | 85 % ~ 110 % |
| Communication interface | RS‑485, Modbus ASCII/RTU |
Before applying power, ensure the AC terminals are not touched and the power source is turned off to avoid electric shock.
Press the lock key to enter Lock 1; press it again to switch to Lock 2. In Lock 2 only parameter changes and reset are allowed.
The device uses RS‑485 and supports Modbus ASCII and Modbus RTU protocols.
The CTA can be powered from AC 100‑240 V 50/60 Hz or DC 24 V, with a consumption of less than 10 W.
