CA-A370-P: 4-Port RS-485 Network Hub
The CA-A370-P allows you to wire an RS-485 network in a star configuration along a new or existing RS-485 network without affecting the performance of the main network or devices connected to it. The CA-A370-P has four slave ports that are completely independent of one another thus providing higher noise isolation from noise and greatly increasing communications reliability.


- RS-485 “star” configuration is a snap
- Provides a higher network isolation from noise
- Saves on wiring costs
- LED indicators for power, network and port activity
- Create 4 independent RS-485 networks
from 1 RS-485 network
- Connects to the CT-V900-A RS-485 and E-Bus
communication ports
- Connect controllers or expansion modules up to 1220m
(4000ft) from the hub
- Power Requirements: 10 to 14.6Vdc
- Current consumption: 190 mA typical
- Operating temp: -10°C to 55°C (14°F to 131°F)
