Mains Supply: Voltage 200-240 V ±10%, 380-500 V ±10%, 525-600 V ±10%; Frequency 50/60 Hz.
Output Data: Voltage 0–100% of supply; Unlimited switching on output; Ramp times 1–3600 sec.
Digital Inputs: 6 programmable inputs, PNP or NPN logic, 0–24 VDC.
Analogue Inputs: 2 inputs, voltage or current modes, scalable levels.
Pulse Inputs: 2 programmable inputs, 0–24 VDC, accuracy 0.1–110 kHz.
Analogue Output: 1 programmable output, 0/4–20 mA.
Relay Outputs: 2 programmable outputs (240 VAC, 2 A and 400VAC, 2 A).
Fieldbus Communication: Supports multiple protocols including Modbus, BACnet, and Ethernet.

Features and Benefits:

All cast aluminium parts are powder coated with epoxy for corrosion resistance.
Stainless steel screws reduce maintenance needs.
Fan designed to withstand corrosion ensures reliable operation.
Unique cooling concept allows operation in harsh environments without ambient air flow over electronics.
Max ambient temperature of 50˚C without derating, eliminating the need for external cooling.
Watertight USB plug for easy setup without opening the drive.

Installation and Usage:

Drives can be installed directly at processing equipment without protective covers.
Stainless steel back plate available for open mounting to guide air from the fan.
For outdoor installations, drives must be protected from direct sun, snow, and ice exposure.

Approvals and Compliance: The drives comply with IEC 60721-3-3 level 3C3 for protection against corrosive gases and have approvals from Norske Veritas, CCl.
