Product Specification 4-Channel Anti-Lock Brake Controller with Traction Control For use with Piloted Pedal Actuated Tandem Modulating Valve Brake Systems Description The MICO 4-channel ABS controller with Traction Control (TC) enhances the effectiveness of a traditional full power hydraulic brake system by increasing stopping and steering control and preventing wheel lock-up under heavy braking conditions. The TC redirects torque from a spinning wheel to the wheels with better traction preventing excessive wheel speed. The ABS/TC controller interfaces with 4-speed sensors to monitor wheel speed, pressure transducers for diagnostics, and four electrohydraulic ABS valves plus one electrohydraulic pilot valve to control the system brake pressure. This system is designed to handle 4-channel ABS/TC control. ABS/TC controllers for 6 and 8-channels of hydraulic ABS (HABS) control are also available from MICO. In addition to these basic components, other inputs and outputs can be added to the system. For example: ABS/TC and brake warning indicator lamps can be added to the outputs of the controller. The MICO 4-channel ABS/TC controller is fully compatible to the SAE J1939 CAN communication standard (sub standards: 11, 21, 71, and 73). MICO is a registered trademark of MICO, Inc.
