COM FOR PRODUCT LITERATURE AND MANUALS Model 12578-003 Monitored Input Module (MIM) Pub. 42004-715L2B Page 2 of 12 Each input may be independently configured to operate in one of the following five modes: Input Mode Description Comments 0 1 2 3 4 5 5 Deactivate circuit IDC line supervision multiple switch IDC single N. O. Detects open circuit, ground faults, and switch actuation from one or more normally-open dry contact closures. [. . . ] IDC Line Supervision Multiple Switch NOTE: The 20 k, 5% tolerance resistor is not included with the MIM. This resistor is included in a kit (12509-003), which must be ordered separately. f:\standard ioms - current release\42004 instr. manuals\42004-715l2b. doc 11/11 Model 12578-003 Monitored Input Module (MIM) Pub. 42004-715L2B Page 6 of 12 Model 2: IDC Single Normally-Open (N. O. ) Switch In this configuration, only one normally-open dry contact closure may be installed per supervised line. In this mode, the loop is monitored for open circuits, wire-to-wire short circuits (across + and -), and ground faults. When the contact closure is not active (open), the loop appears as 20. 1 k load (15 k in series with 5. 1 k). When the contact closure is active (closed), the 15 k resistor is bypassed. Figure 3. IDC Single Normally-Open Switch The circuit then sees only the 5. 1 k load. This changes the value of the input and indicates to the MIM that the contact closure is active. If there is a short across + and -, if either leg is grounded, or if a break occurs on either leg, the MIM indicates that a fault has occurred. These resistors are included in a kit (12509-003) that must be ordered separately. f:\standard ioms - current release\42004 instr. manuals\42004-715l2b. doc 11/11 Model 12578-003 Monitored Input Module (MIM) Pub. 42004-715L2B Page 7 of 12 Mode 3: IDC Single Normally-Closed (N. C. ) Switch In this configuration, only one normally-closed dry contact closure may be installed per supervised line. In this mode, the loop is monitored for open circuits, wire-to-wire short circuits (across + and -), and ground faults. When the contact closure is not active (closed), the 15 k is bypassed and the circuit sees only the 5. 1 k load. Figure 4. IDC Single Normally-Closed Switch When the contact closure is active (open), the loop appears as a 20. 1 k load (15 k in series with 5. 1 k). This changes the value of the input and indicates to the MIM that the contact closure is active. If there is a short across + and -, if either leg is grounded, or if a break occurs on either leg, the MIM indicates that a fault has occurred. These resistors are included in a kit (12509-003) that must be ordered separately.
