Load voltage Max. load current CD-P11 CD-P12 ∗Lead wire length — Auto switch connection side 0.5 m Load connection side 0.5 m 100 VAC or less 25 mA 200 VAC 12.5 mA 24 VDC 50 mA To connect a switch unit to a contact protection box, connect the lead wire from the side of the contact protection box marked SWITCH to the lead wire coming out of the switch unit. Keep the switch as close as possible to the contact protection box, with a lead wire length of no more than 1 meter. Contact Protection Box Connection Contact Protection Box/Dimensions Contact Protection Box Internal Circuit CD-P11 CD-P12 <Applicable switch models> D-A7/A8, D-A7 H/A80H, D-A73C, A80C, D-C7/C8, D-C73C/C80C, D-E7 A, E80A, D-Z7/Z8, D-9/9A, D-A9/A9V, D-A79W The auto switches above do not have a built-in contact protection circuit. A contact protection box is not required for solid state auto switches due to their construction. 1. Where the operation load is an inductive load. 2. Where the wiring length to load is greater than 5 m. 3. Where the load voltage is 100/200 VAC. Therefore, use a contact protection box with the switch for any of the above cases: The contact life may be shortened (due to permanent energizing conditions.) D-A72(H) must be used with the contact protection box regardless of load types and lead wire length since it is greatly affected by loads. (Where the load voltage is 110 VAC) When the load voltage is increased by more than 10% to the rating of applicable auto switches (except D-A73C/A80C/C73C/C80C/90/97/A79W) above, use a contact protection box (CD-P11) to reduce the upper limit of the load current by 10% so that it can be set within the range of the load current range, 110 VAC. Even for the built-in contact protection circuit type (D-A34[A][C], DA44[A][C], D-A54/A64, D-A59W, D-B59W), use the contact protection box when the wiring length to load is very long (over 30 m) and PLC (Programmable Logic Controller) with a large inrush current is used. 2-Color indicator circuit 2-wire (Reed switch) Load 2-wire (Reed switch) Load 2-Color indicator circuit Load Black 2-wire (Reed switch) Load 2-wire (Reed switch) Load 3-wire (Reed switch, NPN) Indicator circuit Indicator circuit 2-wire (Reed switch) Load Contact protection circuit Contact protection circuit Contact protection circuit 2-wire (Reed switch) Load (Power supply for switch and load are separate) Solid state 2-wire Solid state 3-wire, PNP Solid state 3-wire, NPN Load Load Load Load Load Black Black Black Main circuit of switch Main circuit of switch Main circuit of switch Main circuit of switch Main circuit of switch No. No. Brown Blue Blue(−) Brown(+) Load side Auto switch side Choke coil Zener diode Brown Blue Blue( ∼) Brown( ∼) Load side Auto switch side Choke coil Surge absorber Indicator circuit Brown(+) Blue(−) Blue(−) Blue(−) Blue (−) Blue(−) Blue(−) Blue(−) Blue(−) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Brown(+) Blue(−) Blue(−) Blue(−) Blue(−) Solid state 2-wire, Non-polar type 1587 Blue(−) (Brown(+)) Brown(+) (Blue(−)) Main circuit of switch Load Blue(−) (Brown(+)) Brown(+) (Blue(−)) Main circuit of switch Load D- D- C |
