AS-B Onboard I/O
AS-B offers a mix of I/O point types that match most types of HVAC applications. Most I/O points are highly flexible and can be configured as either inputs or outputs.
AS-Bs with 24 I/O points have the following types:
12 Universal inputs/outputs, Ua type
4 Universal inputs/outputs, Ub type
4 Digital inputs
4 Relay outputs
AS-Bs with 36 I/O points have the following types:
20 Universal inputs/outputs, Ua type
8 Universal inputs/outputs, Ub type
4 Triac outputs
4 Relay outputs
The following sections describe the different types of I/O points.
Universal Inputs/Outputs
The universal inputs/outputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.

Digital Inputs
The digital inputs can be used for sensing of multiple dry contact digital inputs in applications, such as equipment status monitoring or alarm point monitoring.

Relay Outputs
The relay outputs support digital Form A point types. The Form A relays are designed for direct load applications.

Triac Outputs
The triac outputs can be used in many applications to switch 24 VAC on or off for external loads such as actuators, relays, or indicators. Triacs are silent and last longer than relays.
