- 1.7.2008 - Ethernet-Controlled Relay: Control 230V / 16A over IP
HWg-ER02a IP Relay is a RS-232 / RS-485 serial line converter with two 230V-rated SPDT relays. The contacts and the serial line can be controlled using the HW VSP (virtual serial port) software, or via the documented M2M protocol. Easily attaches to a suitable panel or a DIN rail.
HW group s.r.o., a Czech Republic based manufacturer of remote control devices, introduces a new version of the popular IP Relay product. The new ER02a can be mounted on a DIN rail, a panel, or a wall. A key feature is the ability to switch 230VAC mains voltage, up to 16A, with two independent relays.

23.4.2008 - PD Trigger: SNMP trap activates outputs, sends SMS
PD Trigger is a Windows application that reacts to SNMP traps with alarm alerts. Alarm reactions are configured similarly to e-mail processing rules. Available actions include displaying a pop-up, launching applications, activating outputs, and sending text messages over a GSM modem.
With PD Trigger, users can avoid the deployment of a complex SNMP NMS, if all they need are simple reactions to received alarms. A limited version supports up to 5 rules and is available free of charge at the HW group website. Commercial versions work with up to 100 rules.
