SLT1 is designed to solve the following tasks:
- collecting information and its primary processing (linearisation, compensation of the influence of external conditions, confirmation of signal reliability);
- issuance of control actions to the executive bodies (EO);
- control of the communication line with the IO for low resistance, short circuit and breakage;
- issuing control actions and receiving information from local control systems;
- processing and storage of information from the control object and control system devices.
SLT1 contains an External Link Module (ELM), which can be supplied to the site in advance to provide convenient and proactive connection to the wiring device.
Cable entry is realised from above through a sealed gland entry, which makes it more convenient to service the device on order.
Connection of RS485 networks is recommended to be made by cable with 120 Ohm wave.
Connection of other circuits is recommended to be made by cable KNRE or similar.
