1. Function

The SDM-CD16AC has 16 AC/DC relay control ports (see Figure 1). Each relay port can be controlled by a datalogger or controlled manually with a manual override toggle switch.

The toggle switch has three positions; "ON" and "OFF" for manual override, and "AUTO" for datalogger control. In the "ON" position, the common (COM) and normally open (NO) contacts are closed (see Figure 2). In the "AUTO" position, the state of the relays are controlled by the datalogger control ports.

The SDM-CD16AC is a synchronously addressed datalogger peripheral. Three ports on the datalogger are used to address the SDM-CD16AC, then clock out the desired state of each of the 16 control ports. Up to 16 SDM- CD16ACs may be addressed, making it possible to control a maximum of 256 ports from the three datalogger ports.

In CRBasic, the SDMCD16AC instruction is used to control the SDM-

CD16AC. In Edlog, either I/O Instruction 104 (CR10(X), CR23X, 21X) or

Instruction 29 (CR7) is used.

NOTE Ensure that the datalogger contains the appropriate instruction prior to system deployment. The SDM-CD16AC is not compatible with our CR200-series, CR500, or CR510 dataloggers.
