Connections

Two modular jacks, J1 & J2 are located on one end of the M2001. Power, input signals, and a normally open output all connect to J1. A complete set of DPDT contacts are available on J2. Refer to the pin-out tables for wiring.

J1 PIN-OUT

J1 PIN NUMBER	TYPE	PAIR	TYPICAL 103 OR 104 BLOCK
1	0-5vdc LOGIC	2	3
2	LOGIC COMMON	2	4
3*	NORMALLY OPEN 2	3	5
4	TIP (+)	1	2
5	RING (-)	1	1
6*	COMMON 2	3	6
7	OPERATING POWER	4	7
8	OPERATING POWER	4	8
*These contacts are common to J2 pair 2.

J2 PIN-OUT

J2 PIN NUMBER	RELAY CONTACT	PAIR	TYPICAL 103 OR 104 BLOCK
1	NORMALLY CLOSED #1	3	4
2*	COMMON #2	2	5
3	COMMON #1	1	2
4	NORMALLY OPEN #1	1	1
5*	NORMALLY OPEN #2	2	6
6	NORMALLY CLOSED #2	3	7
*These contacts are common to J1 pair 3.

Operation

Set the M2001 for the operating voltage with switch 5: open for 48vdc, closed for 24vdc. Select the type of input signal you need to detect and set switches 1 thru 4 as required. Refer to the following list or the option switch table on the previous page. Set the option switches before connecting an input to J1.

• Voltage detect

  Switch 1 closed, switch 2 open, for 4.5sec release delay set switch 4 open. Connect the input voltage to J1 pair 1.

• Ringing detect

  Switch 1 open, switch 2 open, for silent interval holdover set switch 4 open. Connect the input to J1 pair 1.

• Loop current detect

  Switch 1 closed, switch 2 closed, for 4.5sec release delay set switch 4 open. Connect the loop to J1 pair 1.

• Logic level detect

  To detect negative logic set switch 3 open. Input logic level should be 5vdc in idle state. To detect positive logic set switch 3 closed. Input logic level should be 0vdc in idle state. Connect the inputs to J1 pair 2.

Mounting

The M2001 has 2 keyholes for mounting. The keyhole accepts a #4 screw. Locate the 2 screws 2.2" apart.
