Order No. 636-047 1 2 Function Modules—Output Binary Electrical Function Module Introduction The Output Binary Electrical (OBE) Function Module is an interface between the DCM and field devices. This function module provides incremental control of a field device. The OBE Function Module features: ● logic for converting DCM digital output into incremental control signals (+12 VDC) ● Auto/Manual (A-M) switch to enable/disable DCM control ● two momentary pushbutton switches (+ and -) for manual intervention ● feedback indication of the Auto/Manual switch setting to the DCM The OBE Function Module plugs into any one of the bottom ten slots associated with the DCM. Figure 1 shows typical function module locations in the NCU. A five slot panel is pictured. O u tp ut F M s DCMs obe 101 OBE 1 01 Description Figure 1: OBE Function Module Locations Function Modules—Output Binary Electrical Function Module 3 Application Capabilities The OBE Function Module is typically used for incremental control of devices. For example: ● an existing V-9012 ● DC servo driven actuators ● existing Johnson Controls incremental controlled devices Table 1: OBE Function Module Capabilities Capability Description Purpose Input from DCM DCM inputs a digital command. Allows DCM to provide automatic control of outputs. Auto/Manual Switch and Two Momentary Pushbutton Switches Switch selects one of - Auto—DCM control of outputs - Manual—DCM control disabled Pushbutton switches increment/decrement output in both Auto and Manual modes. Allows for manual override of DCM control for special situations. Power on Reset At low power or after power up, output goes to zero. Provides controlled restart. Output to Field Module outputs 2-wire polarized (+12 V/ -12 V) control signal based on input signal. Provides incremental control of field devices. 4 Function Modules—Output Binary Electrical Function Module Allows for local/manual control, even if the DCM is not present. Theory of Operation Figure 2 is a functional diagram of the OBE Function Module. " " OBE DCM Control Electronics Manual Driver A uto Field Device " " obe 101 Figure 2: OBE Function Diagram Under DCM control, the process is: ● ● ● The DCM provides a signal, which increments or decrements the OBE output. Output signal is +12, 0, or -12 VDC. A manually controlled Auto/Manual switch can disable the DCM control of the OBE output. The status of this switch is reported back to the DCM. Two pushbuttons (+ and -) provide manual increment and decrement control. These pushbuttons are functional in Auto and Manual modes. This unit will operate in Manual mode without the DCM present. Power supply must be present.
