1-wire 2 Universal I/O PUZZLE - edgars - 01.07.2015 PUZZLE is a companion product to LM4, LM Re:actor, LM Re:actor Lite and LM Ambient. With PUZZLE you can interconnect regular binary sensors with 1-wire fieldbus or use the device as digital output to control relays/contactors.  By pairing the PUZZLE with LogicMachine, you can finish the installation in very cost-effective way. 2 programmable binary inputs or digital outputs Up to 64 PUZZLE can be connected to one 1-wire port of LogicMachine and all objects can be then managed from any of KNX, Modbus, BACnet etc. devices Perfect solution to integrate cost-effective reed contacts, contactors, water leakage sensors, movement detectors, proximity sensors into smart house installation Compact, stackable design Please see more information here: http://openrb.com/1-wire-2-universal-io/ RE: 1-wire 2 Universal I/O PUZZLE - AWF - 16.07.2015 This unit is very interesting, but from experience the 1-wire protocol using temperature sensors are slow. Updates every minute? 1) Is there any latency for On/Off commands coming from LogicMachine? Or latency from inputs to LogicMachine? 2) How much power/current can it handle? (24V DC relays) RE: 1-wire 2 Universal I/O PUZZLE - admin - 16.07.2015 1. On/off commands from LM are fast, minimum polling time for reading can be set to 1 second. 2. Each port can sink up to 20mA of current which is fine for 24V relays. For example, widely used Schrack relay ratings are: 16.7mA for 16A/250VAC coil or 8.3mA for 6A/250VAC coil. As for temperature sensors conversion time is the main issue. It can be minimized by reading lower resolution values which are more than enough for standard applications like HVAC.
