Frequently Asked Questions
Q: What types of devices can I connect to the inputs?
A: You can connect push buttons, limit switches, proximity sensors, and other dry contact or 24V DC sensing devices.
Q: Can the relay outputs switch both AC and DC loads?
A: Yes, the relay contacts are rated for both AC and DC switching. The maximum ratings differ for each type, so check specifications.
Q: How do I mount and wire this module?
A: Mount on a standard 35mm DIN rail. Use the removable terminal blocks to connect wires. Ensure proper wire size and torque.
Q: What is the difference between this module and solid-state outputs?
A: Relay outputs can switch both AC and DC, handle higher inrush currents, but have limited switching speed and mechanical life compared to solid-state.
Q: From field experience, what helps relays last longer?
A> Using relays within 50% of their rated current significantly extends life. Also, add suppression circuits for inductive loads like motors and solenoids.
