COSMOS PS-8M Cosmos-type gas detection unit (Main Unit)

Target Gas: Combustible gas, Toxic gas, Oxygen

Display:

Monochrome LCD full dot display

Gas concentration: 5-digit display (with units of measurement)

Others: gas name, flow rate status, first and second stage alarm indicator, fault alarm

Digital Signal *1: Ethernet

10BASE-T/100base-Tx (Modbus/TCP)

Modbus/TCP (Maximum number of connections depends on system configuration)

Maximum transmission distance 100m (to HUB)

Gas Concentration Analog Signal *2: DC4-20mA (common negative with power source)

(Output accuracy: within FS ±0.5%)

*0.6mA or less when a fault alarm indication occurs

*The resistance, including wiring resistance, must be 300Ω or less

Combined Gas Alarm Contact (1st and 2nd stage), Combined Fault Alarm Indication Contact *3: 1 non-voltage contact/automatic return

*Rated load: AC125V 0.5A or DC30V 1.0A (resistive load)

*Individual contact outputs require an expansion unit

Operating Temperature and Humidity Range: 0°C to 40°C (with no sudden changes), 30 to 85%RH (with no condensation)

Power Source Used: DC24V ±10% or PoE (Power over Ethernet, IEEE 802.3at)

Dimensions: W70 × H124 × D172mm (excluding protrusions)

Weight: Approx. 850g (excluding sensor)

*1 Modbus-RTU can be used with Ethernet or dispersion unit.

*2 The Main Unit analog output is limited to the Main Unit. The Sub Unit sensor analog output requires the AO expansion module. The AO expansion module can output analog signals from the Main Unit allowing for multiple connections.

*3 When installing two or more sensors using a Sub Unit and using individual contact output, use a DO expansion module. In this case, the individual outputs for the sensors installed in the Main Unit will be output from the expansion unit (the main unit's contacts will be output all at once).
