DX-11,11A,11B,11C type signal relayDetailed product description：

1 Purpose
DX-11,11A, 11B, and 11C signal relays are used as signal indicators in DC operated protection circuits.

Overview of Structure 2
This relay is an electromagnetic relay that can be operated by current or voltage. Relays can be wired in front of and behind the board, and should be installed on vertical panels.
The DX-11 relay has an electromagnet and three sets of movable contact points with a common point, as well as a signal board. The DX-11B relay has an electromagnet, two sets of movable contact points, and a signal board. DX-11A consists of two sets of dynamic contact points and one signal board.
The DX-11C relay has an electromagnetic combination, a pair of movable contacts, and a signal board.
The internal wiring diagram of the relay is shown in Figure 1.

3 Technical data
3.1 The specifications of current type relays in DX-11, 11A, 11B, and 11C signal relays are shown in Table 1, and the specifications of voltage type relays are shown in Table 2.

Rated current (A)	Long term current (A)	Action current (A)	Coil resistance (V)
zero point zero one zero point zero one five zero point zero two five zero point zero five zero point zero seven five zero point one zero point one five zero point two five zero point five zero point seven five one	zero point zero three zero point zero four five zero point zero seven five zero point one five zero point two two five zero point three zero point four five zero point seven five one point five two point two five three	Not exceeding 90% of the rated current	two thousand and two hundred one thousand three hundred and twenty eighty-four thirty eighteen eight three zero point seven zero point three five zero point two

Rated voltage (V)	Long term voltage (V)	Action voltage (V)	Coil resistance (V)
two hundred and twenty one hundred and ten forty-eight twenty-four twelve	two hundred and forty-two one hundred and twenty-one fifty-three twenty-six point four thirteen point two	Not exceeding 70% of the rated voltage	thirty-one thousand and five hundred seven thousand and five hundred one thousand four hundred and forty three hundred and sixty eighty-seven

3.2 The power consumption of current type relays is about 0.3W, and the power consumption of voltage type relays is about 2W.
When the voltage is not greater than 250V and the current is not greater than 2A, the breaking capacity of the contact is 50W in a DC circuit with inductive load (T=5ms) and 250W in an AC circuit (cos&=0.4).
3.4 Dielectric Strength: Each circuit of the relay should withstand AC 50Hz, voltage 2kV for 1 minute without breakdown or flashover for exposed non charged metal parts.
The weight of the 3.5 relay is approximately 0.5kg
The external dimensions of the 3.6 relay are shown in Figure 2.
The installation hole size of the 3.7 relay is shown in Figure 3.
