OREL-01-KIT
The Relay Output Extension module offers three (3) Form C relay outputs numbered RO 4, 5 and 6, rated 2 A maximum current. Switching capacity is 6 A (24 VDC resistive), 1500 VA (250 VAC), Each relay is galvanically isolated from each other (2.5 kVAC, 1 minute). Each relay is programmable.Frequently Asked Questions
What is the purpose of a braking resistor with variable frequency drives?
Braking resistors are required for applications needing faster deceleration or to manage overhauling loads. They increase braking torque and dissipate regenerated power to prevent bus voltage from exceeding drive limits.
What is a braking chopper or module used for?
Braking modules monitor the drive's DC bus and activate external braking resistors to manage regenerated power, preventing over-voltage trips and improving system performance.
How are Powerohm Type CR resistors constructed?
They feature a nickel-chromium wire helically wound inside a ceramic fixture, housed in a corrosion-resistant aluminum case. The element is electrically isolated but thermally bound to the case for efficient cooling.
What is the function of the thermal switch in GCE and ED enclosures?
A normally closed thermal switch is provided in both GCE and ED enclosures to detect resistor temperature overloads.
What wire type is recommended for direct connection to resistors in Type ED enclosures?
If installing without optional terminal connections in Type ED enclosures, always use 200ºC rated silicone or Teflon wire when attaching directly to resistors.
Which ABB drives are compatible with Type CR resistors for single-phase 200-240V applications?
Type CR resistors are available for ACS150 and ACS355 drives in single-phase 200-240V applications, for stopping duty only.
What are the installation features of Type GCE enclosures?
Type GCE enclosures have a solid bottom and a built-in wiring compartment. They include 1/2 inch conduit knockouts for routing standard 90ºC rated wire.
What is the purpose of the internal brake module in some ACS550 drive configurations?
The internal brake module is supplied as standard up to 10 Hp and is optional above 10 Hp for ACS550 drive configurations.
