TWDLCAE40DRF | SOR Compact Base Controller Supplier

What Is the TWDLCAE40DRF Compact Base Controller?

When your automation system demands a reliable and compact controller, the TWDLCAE40DRF from SOR delivers. This compact base controller is part of the Twido product range and operates on a 100...240 V AC supply. It provides 24 discrete inputs at 24 V DC and 16 outputs, including 2 transistor and 14 relay types. With 40 discrete I/O points, it handles moderate control tasks efficiently.

The TWDLCAE40DRF supports up to 7 I/O expansion modules, allowing you to scale your system as needed. Its integrated Ethernet TCP/IP connection (10/100 Mbit/s, RJ45) enables seamless network integration. For serial communication, it offers a non-isolated mini DIN port supporting Modbus/character mode master/slave RTU/ASCII RS485 half duplex at 38.4 kbit/s.

Core Specs and Performance Metrics

• Discrete input voltage: 24 V DC with limits of 20.4...26.4 V
• Discrete input current: 7 mA for I0.2 to I0.5 and I0.8 to I0.23; 11 mA for I0.0 to I0.1 and I0.6 to I0.7
• Input impedance: 2100 Ohm for I0.0 to I0.1 and I0.6 to I0.7; 3400 Ohm for I0.2 to I0.5 and I0.8 to I0.23
• Filter time: 35 µs + programmed filter for I0.0 to I0.5 at state 1; 40 µs + programmed filter for I0.0 to I0.5 at state 0
• Relay output load: 2 A at 240 V AC or 30 V DC (resistive or inductive, 30 cycles/min)
• Mechanical durability: ≥20,000,000 cycles for relay outputs
• Electrical durability: ≥100,000 cycles for relay outputs
• Power supply output current: 0.4 A at 24 V DC for sensors
• Power consumption: 65 VA at 100 V; 77 VA at 264 V
• Program memory: 3000 instructions
• Realtime clock: ≤30 s/month drift over 30 days

One distinctive spec is the filter time variation across input channels. For inputs I0.0 to I0.5, the filter time at state 1 is 35 µs plus programmed filter, while for I0.6 to I0.23 at state 0 it is 150 µs plus programmed filter. This allows you to fine-tune noise immunity for different signal types.

Installation and Setup Guide

Mount the TWDLCAE40DRF on a 35 mm symmetrical DIN rail or a plate/panel with a fixing kit. Ensure ambient air temperature stays between 0...55 °C during operation and -25...70 °C during storage. Relative humidity should be 30...95% without condensation. The unit has an IP20 degree of protection, so install it in a clean, dry enclosure.

Connect I/O using the non-removable screw terminal block. For expansion, use removable screw terminal blocks (up to 152 I/O), spring terminal blocks (up to 208 I/O), or HE-10 connectors (up to 264 I/O). The power supply accepts 100...240 V AC at 50/60 Hz, with limits of 85...264 V and 47...63 Hz. An internal fuse protects the power circuit.

Maintenance and Reliability Tips

To maximize uptime, inspect the TWDLCAE40DRF periodically. Check for loose connections on the screw terminal block and ensure the DIN rail mounting is secure. The relay outputs have a mechanical durability of ≥20,000,000 cycles and electrical durability of ≥100,000 cycles, but verify operation in high-cycle applications.

Monitor ambient temperature and humidity to stay within the 0...55 °C and 30...95% ranges. The unit can withstand vibration of 0.075 mm at 10...57 Hz and shock of 15 gn for 11 ms. Regular inspection per the manufacturer's manual helps prevent unexpected failures.

Compatibility and Integration

The TWDLCAE40DRF integrates via Ethernet TCP/IP (10/100 Mbit/s, RJ45) and a non-isolated serial link (mini DIN, RS485 half duplex) supporting Modbus RTU/ASCII. It also offers a serial link interface adaptor for RS232C/RS485. Use BOOTP client for Ethernet configuration and Modbus messaging for data exchange.

The controller supports up to 7 I/O expansion modules, allowing you to add digital or analog I/O as needed. It also accepts a memory cartridge for program backup. Data is backed up via internal RAM and an external battery (TSXPLP01) with 3-year life.
