|---|---|
| Product Number | AKR2015 |
| Part Number | AKR2015 |
General specifications
| Item | Specifications |
|---|---|

| Operating voltage range | 10.8 to 26.4V DC |
| Current consumption | 200 mA or less (During sending) |
| Inrush current | 23 A (when 24 V DC) |
| Ambient temperature | -10 to +50 degrees |
| Storage temperature | -20 to +70 degrees |
| Ambient humidity | 30 to 85 %RH (at 25 degrees non-condensing) |
| Storage humidity | 30 to 85 %RH (at 25 degrees non-condensing) |
| Breakdown voltage(initial) | 500 V AC for 1 min. (Between power terminal and FG / DSUB connector, Between power terminal and input / output terminal, Between input terminal and output terminal) |
| Insulation resistance(initial) | 100 M ohm or more (at 500 V DC)(Between power terminal and FG / DSUB connector, Between power terminal and input / output terminal, Between input terminal and output terminal) |
| Vibration resistance | 10 to 55 Hz 1cycle / min. Double amplitude of 0.75 mm, 10 min. on 3 axes |
| Shock resistance | 98 m / s2 or more, 4 times on 3 axes |
| Noise immunity | 1000 V [p-p] with pulse width 50 ns, 1 micro s (based on in-house measurements)(Power terminal) |
| Overcurrent protection of power supply | Fuse (Rated current: 3.15A) |

Wireless specifications
| Item | Specifications |
|---|---|
| Wave type | Direct sequence spread spectrum (DS-SS) |
| Transmission distance | Approx. 250 m outdoors (straight, obstacle-free distance), Approx. 50 m indoors (Note) The main unit, standard antenna and antenna with cable are designed for indoor use. If they are used outdoors, then take water-proof measures such as using plastic cases, etc. |
| Wave output | 6 mW / MHz or less |
| Frequency | 2403.328 MHz to 2480.128 MHz |
| Number of channels | 76 ch (Select with communication channel switch) (Note) Adding to the fixed channel, 76 ch (00 to 4B), 89 group channel can be selected. Group channel is the function that it selects connectable channel from several fixed channels automatically. When using repeater function, use with the fixed channel. When using group channel, settable channel numbers are decreased in the same communication area and the communication time becomes longer. |
| Number of channels in same transmission area | 15 channels recommended (when select fixed channel) (Note) It is different according to the mounting conditions, when several channels are used in the same communication area, communication error might occur due to interference radio wave. |
| Transmission speed | 134kbps |
| Communication style | 1: N topology (N: 99 units max.) |
| Repeater function | 8 repeaters (Between master and slave) |
| Response time | OFF to ON, ON to OFF: Max. 80 ms (Note) There are no error without serial communication at 1: 1 topology. Response time: Time from input signal to input terminal to output from output terminal in connected equipment. When input signal is shorter than response time, there is a possibility not to transfer to output side. |
Serial communication specifications
| Item | Specifications |
|---|---|
| Interface | Conforming to RS232C |
| Transmission distance | 15 m |
| Transmission speed | 1,200, 2,400, 4,800, 9,600, 19,200, 38,400, 57,600, 115,200 bit / s (Selectable with MODE switch) |
| Communication method | Half-duplex |
| Synchronous system | Synchronous communication method |
| Transmission format | Stop bit: 1 bit Parity: Not available / Available (odd / even) Data length: 7bit / 8bit |
| Data buffer | 2,048 bytes (Max. data byte size for send and receive one time) |
