The SELCO H300 Event Logger is a compact stand-alone unit capable of logging alarms and events from the M1000C Alarm Monitor, the M3000 Analogue Alarm Monitor, the M4780 and the H1500 Indicator Panels.

• Cost effective solution
• Possibility to monitor all kinds of equipment connected to a common 2-wire MODBUS
• 15 output relays and 1 monitoring output relay

H0400 MODBUS Relay Unit provides a cost effective solution, with the possibility to monitor all kinds of equipment connected to a common 2-wire MODBUS.

The relay unit has 15 output relays and 1 monitoring output relay. Any change of status of any unit on the bus can be programmed to activate or deactivate any one of the 15 relays. The monitoring relay (number 16) has a special function; it is normally energized and will be automatically de-energized if there is a loss of communication with one or more units on the bus.

15 red LEDs indicate if any of the 15 output relays are activated. 1 green LED indicates if the connection to all slave units is ok.

• 10 channels with LED indication
• Supports both NO/NC contacts
• Paper label for alarm description
• Special indication of first alarm
• Programmable reset sequence
• Built-in siren relay
• RS232 based configuration
• RS485 MODBUS-RTU
• Certified for marine use

The SELCO M1000 is an Alarm Monitor capable of surveying the state of up to 10 potential free contacts.

The inputs of the M1000 can be used to monitor both normally open (NO) and normally closed (NC) contacts. Each contact can be sourced to a positive or negative reference. The M1000 includes a total of 10 inputs. Each input controls two bright red LEDs and an open collector output. A built-in relay provides audible alarm through control of an external siren.

• Supports six 3-wire PT100 sensors
• 4-20 mA output signals
• 0-160, 0-300 or 0-600 ºC
• Perfect for use with the SELCO M3000

The SELCO M1500 PT100 6 Way Transmitter includes six current transducers in one box for use with DIN60751 3-wire PT100 temperature sensors.

The output signals from the M1500 are 4-20 mA current signals, which can be easily fed into e.g. an analogue alarm monitor such as the M3000 Analogue Alarm Monitor.

Each sensor input of the M1500 can be configured for three different temperature ranges:
0-160 ºC, 0-300 ºC or 0-600 ºC.

• 24 analogue inputs
• 0-20 mA, 0-10 VDC or 0-30 VDC inputs
• 48 programmable alarm levels
• 24 LEDs for alarm indication
• 14 outputs for relay control
• Output for siren control
• RS485 MODBUS RTU
• Certified for marine use

The SELCO M3000 is a compact 24 channel Analogue Alarm Annunciator. The M3000 is ideal for surveillance of temperature sensors, pressure sensors and any other kind of sensors providing a signal within the range of 0-20 mA, 0-10 VDC or 0-30 VDC.

A linearly pre-scaling is done in order to convert the measured input voltage or current into the entity measured by the sensor (e.g. temperature or pressure). Once this conversion has taken place, all further references are made to the measured entity.

• Compact unit for flush mounting
• 8 input contacts normally open or normally closed
• Time delays 50 mSec. - 15 sec. individually selectable on all channels
• One common output relay for siren and two programmable output relays
   for alarms with voltage free contacts
• LED colour change through plug-in system
• Plug-in terminal block for easy service
• Two integrated push buttons for siren reset/lamp test and alarm accept

The M4100 is a compact 8 channel programmable unit with many features. The 8 inputs will accept any combination of normally open or normally closed contacts. The inputs will cause the appropriate alarm LED to flash and simultaneously activate the common siren relay. Additionally, each input can be configured individually to activate one or both of two alarm relays for group alarm outputs.

Reset performed by the SIREN RESET button will silence the siren, where after it is possible to reset the alarm using the ALARM RESET button. The LED will then change to steady light and is maintained as long as the input signal is present.

Flush mounted unit with standard measurements of 96 x 96 x 75 mm.

• Compact unit for flush mounting
• Programmable LED colour (red, green or yellow)
• Special indication of the first alarm
• 8 input channels (NO or NC contacts)
• Individually LED indication of each of the 8 inputs
• Individually time delay on all channels
• 2 individually blocking modes for easy service
• Special indication of cable break or short circuit

The M4200 Alarm Monitor complements our existing and wide product range of alarm monitors and indicator panels that are used in a number of applications in power plants, ship installations and industrial processes with a demand for a high level of run-time security as well as personal safety.
