Solid-state two-channel relays TTR2-MA…-L2D

It is common for solid state relays to be connected to one control circuit and one load. However, a similar application can be attributed to most electromagnetic relays. However, there is a type of relay that has several relay circuits in one standard housing - the so-called multi-channel relays. Such a solution has a number of advantages. For example, this reduces the cost of products, optimizes the use of working space, etc.

The solid-state relay (SSR) ofthe TTR2-MA…-L2D series produced by CJSC Proton-Impulse is typologically a two-channel relay and has two galvanically isolated switching channels with independent control for each channel. The design of the relay allows you to connect the load with separate channels, or with a common point at the output with independent channel control.

Relay connection diagrams

Relays TTR2-MA…-L2D are made according to the switching scheme with the transition through "0". For overvoltage protection, the relay has a built-in protective diode. The relay is made in an innovative housing and has an LED indication of inclusion.

Overall and mounting dimensions of the relay

The control signal is in the range from 7.5 to 25VDC.
Working temperature and storage temperature - from -40 to 85°S.
The relay does not have a built-in RC circuit (snubber) and varistor, and therefore the maximum peak voltage is limited by the protection circuit and is ±800V.
