GE DS200TCPDG1AFC Ethernet interface card

Signaling unit for the interlock between low and medium voltage To realize an interlock between medium voltage and low voltage, as seen in the previous clauses, it is necessary to use one of the signaling units compatible with SACE Emax circuit-breakers. These units allow remote signaling of circuit-breaker alarms and trips and can be set by the user by means of the test and signaling unit PR010/T or the programs SD-Pocket (for PDA) or SD-TestBus (for PC). Reference must be made to the previous clauses for the setting of the contacts PR021/K signaling module converts the digital signals of the protection units into electrical signals via 8 normally open contacts. For the proper functioning a 24V DC supply is needed: since an earth-insulated auxiliary voltage is required, it is necessary to use “galvanically insulated converters” complying with the Standards IEC 60950 (UL1950) or any equivalent device.

PR021/K module 

shall be connected to the internal bus of the trip unit, through the slots W3 and W4 of the terminal box (the figure shows the terminal box of a withdrawable circuit-breaker type Emax)PR021/K module shall be mounted on a 35 mm standard DIN rail. For the removable front connectors of the module, the cables to be used shall have a cross section in the following range: - 0.5 and 1.5 mm2 (AWG 22…14) for the connection to the clamps 1…10; (left side of the module); - 0.5 and 2.5 mm2 (AWG 22...12) for the connections to the terminals 11…26 (on the right side of the unit).

The internal signaling module PR120/K 

(mounted on the back part of the release) is supplied by trip units (in case the auxiliary supply is provided on it) or by PR120/V voltage module. PR120/K is equipped with four trip units, whose contacts are called K51/p1, K51/ p2, K51/p3 and K51/p4. These contacts can signal different events which can be selected by the user among those included in the standard list; however, the user can associate to the 4 contacts “customized” events by selecting “Custom” from the menu and setting the required signal through PDA, SD-Testbus or PR010/T. The outputs on the contact terminal box are identified by the terminals K4,K6,K8,K10.
